Aiphone LEF-5C Master Intercom Station 5-channel

Product Description

The AIPHONE LEF-5C is an open-voice, selective-call master intercom station designed for multi-room and multi-door audio communication systems. It provides two-way audio between a master station and up to five connected door or sub-master intercom units. Built-in LED-indicator buttons let the installer direct calls to specific intercoms with precision. The station includes an all-call button for broadcasting messages or music to every connected unit when paired with an Aiphone BG-10C adapter, and a dedicated door-release button for electric-strike access control when used with an Aiphone RY-PA relay. Licensed low-voltage technicians and commercial communications installers typically handle setup and wiring.

The LEF-5C is suited for residential and light-commercial intercom systems where selective-call functionality and door-release control are required. It works with any combination of up to five Aiphone LAF and LEF Series master intercoms or LA, LE, and LS Series door and sub-master intercoms. Typical applications include apartment entry points, office suites, and multi-room facilities where staff need to screen visitors at a door and communicate across rooms from a central master station.

Installation Notes

Installation is typically performed by a licensed low-voltage or communications technician familiar with intercom wiring practices.

Each intercom station in the system must be connected to its own Aiphone RY-PA relay for access control and auxiliary device integration. Consult local electrical codes and the manufacturer wiring diagrams before commissioning the system.
